engine and server logs

Description of problem:
[RFE] - ovirt-engine service fails to start,  but systemd is unaware of that and consider it as running.

-We should report ovirt-engine service as active/running only if engine ear is actually deployed to jboss, not only when jboss server is running.

Version-Release number of selected component (if applicable):
4.0.0-0.0.master.20160423161403.gite38df80.el7.centos
systemd-219-19.el7_2.8.x86_64


Steps to Reproduce:
1. Enter to engine DB and insert a fake MAC pool id without range:
engine=# insert into mac_pools (id, name) values ('19479b7e-0ac5-11e6-a513-68f7280ce233', 'fake');
INSERT 0 1
2. Quit DB and restart ovirt-engine service
3. Run systemctl status ovirt-engine and try to login the engine UI

Actual results:
[root@dhcp160-211 ~]# systemctl status ovirt-engine

- But engine UI isn't accessible. Engine actually fails to start and systemd isn't aware of that. 

Expected results:
Engine should fail to start and systemd should be aware of that
